Design and Techno-Economic Evaluation of a Hybrid Mini-grid System for an Academic Institution

Received: 26 September 2023;  Published: 03 April 2024;  doi: 10.21926/jept.2402010

Abstract

Inadequate electricity supply is a global challenge that needs solutions. This situation has compelled the purchasing of fossil fuel-generating units for use in residential, commercial, and industrial sectors to generate electricity. However, using fossil fuel generating units cause greenhouse gas e [...]
